Abstract

Laser desorption ionization Fourier transform ion cyclotron mass spectrometry (LDI–FTICRMS) was used to investigate particulate matter (PM) associated to mainstream (MSS) and sidestream cigarette smokes (SSS). The high mass resolution and the high mass accuracy allowed a molecular formula for each detected signal in the 150 – 500 m/z to be assigned. The high number of peaks observed on mass spectra required additional data processing to extract information. In this context, Kendrick maps and Van Krevelen diagrams were drawn. These post acquisition treatments were used to more easily compare different cigarette smokes : (i) MSS from different cigarettes and (ii) MSS and SSS from the same cigarette.

In both ion detection modes, the main part of the detected species were found to be associated to C6-31H2-35N0-7O0-9 compounds. The compounds observed in the study of SSS appeared to be more unsaturated and less oxygenated than those observed when MSS of the same cigarette were investigated.
